A solid four hour drive from Hood River, this spot is often well worth the effort. Head south on I-5 from Portland through Salem and starting looking to exit just prior to entering Eugene. Take exit 195A and proceed west on Beltline Rd. Continue on Beltline Rd. it will turn toward the south and end at RTE 126 (10 miles), this will go from 4 lane highway down to a 2 lane road right before the RTE 126 junction. Turn right (west) towards Veneta and continue west on RTE 126 all the way to the intersection w/ RTE 36 at the Siuslaw River (Mapleton). Turn left (south) on RTE 126 and continue westward towards Florence. After 25 minutes of RTE 126 or so, you will come into the town of Florence. To reach the South Jetty, turn left (south) on HWY 101 and drive just over the Siuslaw River Bridge. Just at the top of the hill, turn right into the National Dunes Recreational Area Park. Proceed straight another 3 miles to the end of the jetty, use your best judgement when parking - it will be a costly trip if you have to call a tow truck.
